Multi-Query Filtering

Overview

It's possible to filter Map Layers in a number of ways

Filter by Values

To filter a Map Layer based on values

  1. In the Layer Control, find the layer you want to filter and switch it on
  2. Hover over the Tick icon next to the Layer name. This turns into a Cog. Click the Cog/Layer settings icon.
  3. In the Layer mini-menu, click Filter


Single Queries
  1. From the 'Filter Column' drop-down, choose the column of information stored within that layer that you want to filter on.
  1. In the Operator drop-down, choose from:
    • Equals (will only display objects that exactly match the value entered in the next step)
    • Starts With (will only display objects that start with the value entered in the next step)
    • Ends With(will only display objects that end with the value entered in the next step) 
    • Contains(will only display objects that contain the value entered in the next step) 
  2. In the 'Filter Value' text box, enter the value you require. Note: this may be a drop-down limiting your choice of options
  3. Click Save











Multiple Queries
  1. To add a second filter query, click on ADD FILTER
  2. You can have up to five filters 
  3. Queries can be created to match again ALL matching filters - much like an AND statement.
  4. Queries can be create to match against ANY matching filters - much like an OR statement.
  5. Click Save


Filters can be edited or removed via the layer settings tool



Clearing a Filter

To clear a Filter:

  1. Find the layer in the Layer Control

Filter by Selection

To filter a Map Layer by selection:

  1. In the Layer Control, find the layer you want to filter and switch it on

    • HINT: You can select multiple Map Objects by holding down the CTRL keyboard button whilst clicking on the map. When selecting multiple objects, the attribution won't show on the left-hand side.
  3. In the Info Click panel, click the Filter icon.
